This study identified morphotype-specific gene expression patterns in feathers, enhancing understanding of the molecular and cellular processes involved in feather development and diversification.

This study identified that bone marrow-derived CD34⁺ cells act as fibroblast progenitors to enhance tissue regeneration in ischemic limbs by promoting angiogenesis through interactions with macrophages.

In this review, biomaterial-based mechanical strategies were highlighted for their potential to enhance skin regeneration and promote scarless repair, though a comprehensive understanding of their underlying mechanisms is still needed for broader application.

This study found that SIRT1 negatively regulates fibroblast activation and excessive scar formation, suggesting it may be a promising drug target for treating hypertrophic scars.

This article discusses the use of platelet-rich plasma as a supportive treatment for hair loss, emphasizing its potential to enhance hair follicle health and patient satisfaction, but reports no new clinical results.

This review highlights the potential of scaffold-based drug delivery systems to revolutionize oral cancer treatment by enhancing targeted and localized drug administration, reducing systemic side effects, and providing environments conducive to non-cancerous cell growth, though challenges like scalability and biocompatibility remain.

This review focuses on the role of the transcription factor Foxn1 in skin biology and discusses its potential implications for regenerative medicine, but reports no new clinical results.

This review highlights silk fibroin and its nanocomposites as promising materials for wound healing, addressing challenges in chronic wound treatment, especially in developing countries, and examines the obstacles in bringing silk-based products to market.

This review discusses nitric oxide's physiological roles and the development of strategies for delivering it exogenously, without presenting new clinical results.

In this review, the authors discuss the promising role of exosomes from various cell sources as potential cell-free therapies for diabetic foot ulcers, highlighting their therapeutic benefits in wound healing and the challenges faced in their clinical application.

This study found that a combination of natural compounds (escin, bromelain, ginkgo biloba, and sage miltiorrhiza) reduced platelet adhesion to activated endothelium in laboratory settings by inhibiting adhesion molecule transcription and reducing pro-inflammatory cytokines, potentially preventing initial steps of the coagulation cascade.

This review article highlights the potential of mesenchymal stem cells, their exosomes, and non-coding RNAs in repairing aging skin tissues due to their ability to secrete beneficial compounds, suggesting their promising role in photoaging treatment without causing immune rejection or granuloma formation.

This article reviews the emerging non-inflammatory roles of regulatory T cells in the skin and reports no new clinical findings, suggesting broad biological influence beyond traditional immune functions.

This review summarizes recent insights into corneal limbal stem cell differentiation and the potential role of progenitor-like cells, but reports no new experimental results.

In this study, researchers found that retinoic acid is crucial for hair follicle stem cell function and tissue regeneration by resolving lineage plasticity, with potential therapeutic implications for hair growth, wound healing, and cancer.

In this study, human dermal fibroblast-conditioned medium was found to contain numerous proteins involved in wound repair and hair regeneration, with identified proteins forming interaction networks linked to key signaling pathways like epidermal growth factor receptor and transforming growth factor-β.

This study reports that blocking the epidermal growth factor receptor in cancer treatments can lead to changes in hair growth and create a "wavy" hair phenotype in some patients.

This review concludes that while many epidemiological studies suggest high alcohol intake is associated with an increased risk of prostate cancer, the evidence may be affected by confounding factors such as diet and lifestyle.

This study found that low oxygen conditions and ECM degradation products increased the proliferation and migration of perivascular stem cells without altering their phenotype, suggesting potential roles in tissue repair.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

This study found that the creation of hair follicle lumens in mice is driven by the outward migration of keratin 79-positive cells, suggesting a novel mechanism for generating hollow cores in hair follicles.

This review discusses the identification and roles of different epidermal stem cell types in skin homeostasis and repair, and reports no new experimental findings.

This article reviews the classification and treatment of cutaneous manifestations in systemic lupus erythematosus, highlighting the importance of monitoring for disease progression and reports no new clinical results.

This research concluded that the novel hydrogel PlacMA, derived from human placenta and curable by visible light, shows promise for cell culture and tissue engineering applications due to its tunable properties.

In this study, researchers observed that dysregulated innate lymphoid cells type 1, alongside CD8+ T cells, may contribute to the pathogenesis of alopecia areata by affecting hair follicle health.

This study identified a distinct cytokine activation signature in alopecia areata, involving TH2, TH1, IL-23, and IL-9/TH9 pathways, suggesting potential targeting strategies similar to those in psoriasis and atopic dermatitis.

This study found that Thy1+ keratinocytes in the basal layer of the interfollicular epidermis play a crucial role in epidermal homeostasis and wound repair, with their ablation impairing these processes.

This study found that inducing miR-205 reduces actin contractility and stiffness in hair follicle stem cells and progenitors, stimulating hair regeneration in both young and old mice.

This study provides evidence that innate lymphoid cells-type 1 can induce alopecia areata in human hair follicles, challenging the view that it is solely a CD8+ T cell-driven autoimmune disease.

This volume is part of a series intended to educate plastic and reconstructive surgeons, residents, and other medical professionals, but the abstract does not report specific research findings.
